Another Is this one or that one better Question?: Sony DSC-V1 vs. Pentax optio 550

Im looking for a compact camera (5 mega pixel or better), the best I can get in the sub $700 range.
The Fuji is not out yet, and I still have reservations about the actual pixel count for the purpose of large blow-ups (though it may be great for dynamic range) This leaves me with the Pentax Optio 550, which has been said to have noise problems at higher IOS settings, and the Sony DSC-V1 which is said to have some sort of color problems. I am pretty familiar with the features of both, so my real question is which will take higher quality pictures?????
Anybody have any experience with both of these together, or anyone else who has an opinion?

P.S. I often have my girlfriend carry it in her purse when we are out, so a DSC-717, Nikon 5700, Fuji 602 is out (unless I want to drag it around myself) Yes, I know I’m lazy.
